<p>The Elastic Stack security features use three <em>internal</em> users (<code class="literal">_system</code>, <code class="literal">_xpack</code>,
and <code class="literal">_xpack_security</code>), which are responsible for the operations that take place
inside an Elasticsearch cluster.</p>
<p>These users are only used by requests that originate from within the cluster.
For this reason, they cannot be used to authenticate against the API and there
is no password to manage or reset.</p>
<p>From time-to-time you may find a reference to one of these users inside your
logs, including <a class="xref" href="auditing.html" title="Audit logging">audit logs</a>.</p>
